Robo Pong the robot that throws the ball in table tennis

Robo Pong by Newgy is a robot which can train you in table tennis by throwing the ball to you. Along the same principle as ball throwers in tennis, Robo Pong throws the ball to you at regular intervals. The big advantage of this machine is that it also retrieves the balls that you return to it and therefore provides you with unlimited exchanges.
